[译] 我的妹妹总是向我抱怨功课重。
[误] My sister is always complaining to me for her heavy schoolwork.

[正] My sister is always complaining to me of her heavy schoolwork.
[注] complain 后面应接 to + somebody + of + something,也可接“about + something(somebody)”，但不可接 to + somebody + for + something。如: He called the waitress and started complaining about the service.他把女侍者叫来，开始抱怨服务欠佳。
